Frequently Asked Questions

What is a Unix timestamp?

A Unix timestamp is the number of seconds elapsed since January 1, 1970 00:00:00 UTC (the Unix epoch). It's a universal way to represent time in computing.

What's the difference between seconds and milliseconds?

Unix timestamps in seconds are 10 digits (e.g., 1700000000), while milliseconds are 13 digits (e.g., 1700000000000). JavaScript uses milliseconds, most systems use seconds.

Does this tool handle timezones?

Yes. The tool shows both UTC and your local timezone when converting timestamps, so you can see the exact time in both.
